I think I managed to fail the fastest.
Did you know that if you clip the exact corner of a platform while in freefall, you just stop dead in your tracks and cannot move in any direction? And if you don't have an ability to save you, like, say... at the start of the bounce pad levels, you're functionally softlocked, because the game lacks any form of 'reset' button!
Because, for better or for worse, now I know that.
